public class Date extends Date
A thin wrapper around a millisecond value that allows JDBC to identify this as an SQL DATE
value. A milliseconds value represents the number of milliseconds that have passed since January 1, 1970 00:00:00.000 GMT.
To conform with the definition of SQL DATE
, the millisecond values wrapped by a java.sql.Date
instance must be 'normalized' by setting the hours, minutes, seconds, and milliseconds to zero in the particular time zone with which the instance is associated.

Constructor Detail
Date
@Deprecated(since="1.2") public Date(int year, int month, int day)
Date(long date)
Constructs a Date
object initialized with the given year, month, and day.
The result is undefined if a given argument is out of bounds.
- Parameters:
-
year
- the year minus 1900; must be 0 to 8099. (Note that 8099 is 9999 minus 1900.) -
month
- 0 to 11 -
day
- 1 to 31
Date
public Date(long date)
Constructs a Date
object using the given milliseconds time value. If the given milliseconds value contains time information, the driver will set the time components to the time in the default time zone (the time zone of the Java virtual machine running the application) that corresponds to zero GMT.
- Parameters:
-
date
- milliseconds since January 1, 1970, 00:00:00 GMT not to exceed the milliseconds representation for the year 8099. A negative number indicates the number of milliseconds before January 1, 1970, 00:00:00 GMT.
Method Detail
setTime
public void setTime(long date)
Sets an existing Date
object using the given milliseconds time value. If the given milliseconds value contains time information, the driver will set the time components to the time in the default time zone (the time zone of the Java virtual machine running the application) that corresponds to zero GMT.
- Overrides:
-
setTime
in classDate
- Parameters:
-
date
- milliseconds since January 1, 1970, 00:00:00 GMT not to exceed the milliseconds representation for the year 8099. A negative number indicates the number of milliseconds before January 1, 1970, 00:00:00 GMT.
valueOf
public static Date valueOf(String s)
Converts a string in JDBC date escape format to a Date
value.
- Parameters:
-
s
- aString
object representing a date in in the format "yyyy-[m]m-[d]d". The leading zero formm
anddd
may also be omitted. - Returns:
- a
java.sql.Date
object representing the given date - Throws:
-
IllegalArgumentException
- if the date given is not in the JDBC date escape format (yyyy-[m]m-[d]d)
toString
public String toString()
Formats a date in the date escape format yyyy-mm-dd.
- Overrides:
-
toString
in classDate
- Returns:
- a String in yyyy-mm-dd format
- See Also:
-
Date.toLocaleString()
,Date.toGMTString()
getHours
@Deprecated(since="1.2") public int getHours()

setMinutes(int)
getSeconds
@Deprecated(since="1.2") public int getSeconds()
This method is deprecated and should not be used because SQL Date values do not have a time component.
- Overrides:
-

in classDate
- Parameters:
-
i

valueOf
public static Date valueOf(LocalDate date)
Obtains an instance of Date
from a LocalDate
object with the same year, month and day of month value as the given LocalDate
.
The provided LocalDate
is interpreted as the local date in the local time zone.
- Parameters:
-
date
- aLocalDate
to convert - Returns:
- a
Date
object - Throws:
-
NullPointerException
- ifdate
is null - Since:
- 1.8

instance using the year, month and day from this Date
object.
- Returns:
- a
LocalDate
object representing the same date value - Since:
- 1.8

values do not have a time component.
- Overrides:
-
toInstant
in classDate
- Returns:
- an instant representing the same point on the time-line as this
Date
object - Throws:
-
UnsupportedOperationException
- if this method is invoked
